Boeing is having a rough time of it right now, with parts falling off its planes left, right and center. Just last week, a wheel came loose and smashed through a car, and earlier this year the door from a 737 Max aircraft broke off mid-flight. That mid-air disaster sparked an audit from the Federal Aviation Administration, which has gone far from well.
The issue with those items is that they are not in the list of approved materials for Boeing’s manuals. It might be normal to see these sort of practices in a line maintenance environment where it’s hard to get the proper tooling; but the manufacturer should be abiding by it’s own regulated publications. It’s just more symptoms of their cost cutting and schedule rushing measures that are leading to their quality issues.
My company has been spending a lot of time and money doing warranty repairs on brand new airplanes that we received from Boeing over the past couple of years. It’s very concerning when a customer has to fix things that should have never left the factory floor.
